Benchmarks show GCC 16 is producing faster binaries than GCC 15 whilst in a very tight race against Clang 22

It's a bit sad GCC isn't that used or Supported outside C/C++ not as LLVM

Not an expert, but I thought the llvm backend was generally a better optimiser than the gcc backend

Was It? I though there was almost no difference but LLVM was slightly worse but faster

But still in case of using LTO and PGO and other serious optimizations GCC can't compete with Clang. IMO Clang is still faster and in heavy optimized cases even more.

the fact that GCC is still trading blows with Clang after all these years is pretty healthy for the ecosystem

I was ready to see some very minimal improvements as is often the case in Phoronix benchmarks and was actually surprised by how substantial some of those these look.

I really wish they showed any indication about the distribution of the samples in these graphs though... The geometric mean is good, but it's difficult to interpret if close results are just the result of random sampling or actual minuscule improvements.
